Selection of promising materials for centrifugal nozzles of injecting steam coolers

https://doi.org/10.46973/0201-727X_2024_1_240

Abstract

   Based on the results of the analysis of information on the destruction and defects of centrifugal nozzles of injection steam coolers (VPO), it was identified the need for selecting a promising material for their manufacture in order to increase their service life. It was described a fundamental approach to carrying out full-scale testing of samples as close as possible to the operating modes of centrifugal nozzles in injection steam coolers including cyclic heating and cooling. Criteria were determined for selecting a promising material for the manufacture of centrifugal nozzles, namely: the structure of the material and the change its hardness, as well as its tendency to crack.
